Last week I noticed that tips of younger top leaves are getting yellow. I suspect the light burn but not 100% sure. Do photos look like a light burn to you?
It looks like nitrogen toxicity. Just feed less nitgrogen and i think they should be just fine. But don't forget to watch the ph if you feed them less/nothing suddenly. Sometimes that can cause a fluctuation in ph, to which some plants can react negatively. happy growing buddy 🌱🌞🍀
@timon, Or just give them like 25% or something like that. But for the next two feedings and observe how they react.😊 They'll be fine! good luck and happy growing buddy 🌱🌞🍀
